2.25 Use quotation mark-up for quotations, but not for formatting
WAI checkpoint 3.7
Full WAI text: "Mark up quotations. Do not use quotation mark-up for formatting effects such as indentation." HTML allows you to mark-up quotations from external sources and publications. These will then be displayed in an appropriate way.
Text which is a quotation should be marked up as a quotation, rather than having quote marks and indentation specified as attributes. Text which is not a quotation should not be marked up as a quotation for the sake of visual presentation. For example, you should not mark-up text as a quotation as a means of displaying it within quotation marks.
Correct use of the quotation mark-up can break the page into chunks of content which helps users to read content more easily on-screen.
Some screen readers will read content assigned as a quotation in a different tone of voice, providing users with important clues about document structure. Misusing quotation attributes will therefore confuse screen reader users.
Directions and Techniques
Use "Q" and "BLOCKQUOTE" elements for inline and block quotations, respectively.
The "Q" tag should be used within a paragraph to quote a direct source. The "BLOCKQUOTE" tag should be used for longer quotes, which are "blocked" or indented from the page margins. See the WAI recommended techniques for Marking up quotations
